To all whom/it may concern:

Be it known that I', CORDA A. HART, a citizen of the United States, residing at Dan:

villa, in the county of Vermilion and State of Illinois, have invented certain new and useful Im rovements in Motor-Plows, of which the fol owing is a specification.

,Thisin'vention embodies improvements in that type of agricultural implements propelled'by' a motor mounted u on the im lement, andilesigneil particular y for plowing. In the practical embodiment of the invention 1t is contemplated that the plow shallbe driven-by an engine of the explosive type,

and included among theessentialfeatures of V the. invention is peculiar mechanism whereby 1 the low or plows mounted on the frame of the nnplement maybe adjusted-to throw the same into andout ofoperatiori or to accom- ,modate forinequalities in the "ground overwhich the implement passes.

i The invention further involves novel details of construction-as will appear more fully l. e hereinafter.

For a full understandin of the invention,

, reference is to be hadto t e following-detail description and tofthe accompanying drawings, in which i erence characters, h v U Referringto the drawings and describing 1 Figure 1 is a top plan view of an implementembodying themventionyFig. 2 is a side elevation; Fig. 3 isa detail perspective view of the plow adjusting shaft; Fig. 4 is a detail perspective view of the socket receiving an end of the transverse shaft. j

Throughout the following detail descrip tion and on the, several-figures of the drawings, similar parts are referred to by like refs ecifically the construction of the invention,

t e numeral 1 designates thefra-me of the implement, which is preferably of rectangular form, being supported at its front ortion by, an axle 2 mounted on ground w eels 3.

At its rear end the frame 1 is carried by a, steering wheel 4 supported in a bifurcated standard 5. The standard 5 is rovided at its upper end with a reduce for turning movem nt in order to vary the journal 6 mounted in a suitable bearing provided in the frame, whereby the wheel .4. is adapted direction of travel 0 the im lement.

. ,{Ihe operating means or the steering Wheel, 4 comprises a frame 7 consisting of I indivergent relation and"considesarran e v Dected at t e remote ends thereof by an arch? ed plate 8 which is adapted to cooperate suitable uiding means 9 attached to the frame 1. 8 the o posite sides of the frame 7 are connected-- y a toothed bar 9 between which and the plate 8 is arranged a horizontal gear 10 the teeth of which mesh with the teeth of the bar 9. 4 The gear 10 is attached to the lower endof a steering shaftll mounted in any substantial manner upon the frame 1 of' the implement and having at its upper end a suitable hand wheel 12. The rear end of the frame 7 is formed with an o ening adapted to receive the journal 6, an suitable fastenings are provided to attach this portion of the frame 7 to the u per end of the standard 5. Upwardly inc med braces ome distance from the plate 13 maybe usedto connect, the lower end of.

thestandard 5 with the front portion of the franie 7. '-It will be ap arent that by rotation of the hand wheel 12 the direction of movement of the implement may be varied at the will ofthe o eratoliwho is seated upon-the seat 14, w en the implement is being used. I,

Themotor b which the implement is'prop'elledlsprefera ly mountedupon theforward portion of the frame 1 and consists of an explosive en ine 15. ,.The engine 15 may be of any suitab e horse power according to the size of the implement with reference particularly to the number of plow shovels carrled thereby.

train of gearing with the power shaft of the motor 15 and'the o eration of the implement will be contro led by any suitable mechanism operable from the seat 14 so as to permit of starting or-stopping the plow at any time Pivotally and adjustably connectedwith the front end of theframe 1,, as

, The front axle 2 is connected by a suitable shown at 16, are aplurality of beams 17, the

rear ends of which support the turning plows 18. Any suitable riumber of the earns 17 may be provided within-the contemplation of the invention.

Arranged transversely of the frame 1 about at the middle portion thereof is a crank shaft 19 which is (peculiarly mounted to admit of special a j ustment of the turning plows 18. Said shaft 19 is formed at one. end: with a ball 20-received by a socket 21 in a socket plate 22 secured to'one side of the frame '1. The op osite end of the shaft 19 is formed witha ead 23 which is movable posite side of the frame 1. In other wor 8 vertically, in a guide 24 secured to the 0 i by a seg the shaft 19 has a ball and socket connection atone end with a side of the frame 1 while its other end is slidably. mounted upon the opposite side of the frame. Arms roject laterally from the shaft 19 and sai arms are donnected by links'26 with the beams 17.

Extending upwardlyfrom the end of the shaft adjacent to the ball and socket con-' nection 20 and '21 is a crank' arm 27 connected'by a rod 28 with a lever 29 mounted upon the adjacent side of the framel and Another adjusting mech mm for the shaft 19 is provided and is mounted-upon the framel at the side opposite that carrying the adjusting device above'described. This adjusting mechanism comprises a bell crank lever 31 pivoted to the frame 1 at the side adjacent to the guide plate 24. The vertiea arm of the lever31 1s connected by a rod 32 with an- 0 crating lever ,33 being also adapted to be eld at a desired adjustment.

ment cooperating with pa catch on the ever; The horizontal arm of the bell crank lever 31- is-formed with an elon gated opening or slot 34 sufficiently large to receive the end portion of the shaft 1% ma cent to the head 23 thereof. It will be obvi O't'aS that by operation of the lever 33 the bell crank lever 31 may be tilted so as to raise or lower the end of the shaft 19 which operates in the slot-34 and is movable longitudinally of said slot in an evident manner. Adjustment of the bell crank lever 31 therefore admits of adjustin the end of the shaft 19 co'nnected therewi without raising or lowering the opposite end of the shaft, and by this means said shaft may be inclined with reference to a-horizontal plane.

It will be a parent in view vof the forego- 5''10 that the s aft 19 is so mounted and con nult'aneously lowering or raising t e beams,

spent to the other, or to accomplish other mbined adjustments such as may be denie and necessary in the actual oeration he implement, either to throw t e turnplows 1'8 into and out of operation, or to adjnst'the relative ositions of'said turning plows to accommodate forinequalities in the groundover which the implement is ad vanced. v 4

i The various advantages of the construe --tion"embodied in my invention will be evident in view of the. detail description herein- 3 IL 1'" in 111s 11nrlnvafnnri .ed with the beams 17 as to ermit of to elevate-or lower one of the beams with reconstruction and arrangement of the various parts may be modified in accordance with the broad s irit of the invention.
